Pressure switch and insulin delivery device

The utility model relates to a pressure switch and insulin delivery equipment. The pressure switch includes: an upper plate; the base plate is opposite to the upper plate, and an opening communicated with a fluid path is formed in the base plate; an elastic membrane arranged such that pressure from the fluid within the fluid path deforms the elastic membrane toward the plunger, thereby moving the plunger. A plunger is disposed between the elastic membrane and the upper plate and is movable along an axis extending between the elastic membrane and the upper plate. A threshold pressure on the elastic membrane from fluid within the fluid path deforms the elastic membrane, thereby moving the plunger toward the upper plate. 本公开涉及一种压力开关和胰岛素输送设备。所述压力开关包括：上板；与所述上板相对的基板，所述基板中具有与流体路径连通的开口；弹性膜，所述弹性膜布置成使得来自流体路径内的流体的压力使弹性膜朝向柱塞变形，从而移动柱塞。柱塞设置在所述弹性膜和上板之间，并且可沿着在所述弹性膜和上板之间延伸的轴线移动。所述弹性膜上的来自流体路径内的流体的阈值压力使所述弹性膜变形，从而使柱塞朝向上板移动。
